l Be it known that I, SIDNEY PARKER, of Chicago, in the county of Cook, and State'of Illinois, have invented i certain new and use ful improvements in Railroiid Frogs; and' Iv do hereby declare that the following'is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference marked'thereon-rlike letters indicating like parte wherever 'they occur. Y

l To enable others skilled in the art te construct and use theinvention, I will proceed to describe it.

' My invention consists in -making a hed-'piece or frame of a single piece ofcost iron, of proper shape to receive and hold the rails, and ttingthereto rails of cast steel, with a packing between them ci1 rubber or other yielding substance. i

Figure 1 is a side elevation. Figure 2, a top plan'vew. Figure 3, a longitudinal vertical section on the line A B of lig. '2. ignre 4, a. bottom plan view. Figure 5, an end elevation, lookingfrom the line G H. i Figure 6, a transverse vertical section on the line C D of figs. 1 and 2; vend '-,Figure 7, an end eleva-tion, looking from the line'E Fof lig. 2.

*iirstcnstruct a bed-piece or frame, B, the form of which is shown clearly in g. 4. lrojectonsor-arms,l Lproject laterally from euch side, in order to give it a broad, irrn4 bearing, as represented in the-drawings.

Atflih' end this bed-piece, B, is provided with vertical projections, c', which serve the twofold purpose of forming 'fachairftoreceivo the end of the adjoining rails, and also assist to hold the plate A of the frog in place. A represents a plate 'of cast iron somewhat shorter than the plate B, and which is placed directly on the plateB, 1 "the latter 'projoctingat each end far enough to form a. chair, as above described, to receive theend of the adjoin- 'ing rails. On its upper surface this plate, A, has grooves formed in it, of the proper size and'shape to receive the rails of ythe frog, which I make of cast steel.- A .layer or packing of rubber, leather, brother suitable material, is placed in the grooves, and the rails being placed thereon, the wholeis firmly bolted together by'bolts, e, represented in the drawing. Whenever the frog becomes worn the rails can be detached and new ones substituted, or vthe plate -.A., with its railsca'n be removed and a new one substituted without in any manner interfering with the bed-plate B or the adjoining rails. Bythese means I ani enabled to construct a frog that is exceedingly strong, durable, and lsimple, and thus greatlyl to improve the construction of railways, andlessen the liability tojiccidents by ydisplacement or breakage of the arts. greatly increases the wear and durability of tho-rails. Having thus described my invention, what I claim is i A railroad frog,consisting of 'the bed-plate B, plate A, and the steel rails in, y, and z, combined and constructed as herein shown and described.
